10 x 13 Open End Envelopes Teal - Flat Document Mailers

In this review the 10 x 13 Open End Envelopes in teal are evaluated as a practical choice for anyone who regularly ships flat, bulky documents without folding. The reviewer found the pack of 500 particularly useful for offices handling catalogs, annual reports, W-2/1099 forms and direct mail where preserving the document condition matters most. The standout reason to buy is durability and a professional presentation: these envelopes are made from heavier 80lb. text stock and use a peel & press closure that speeds up large mailings while keeping contents secure.

Key Features

• Size: The 10 x 13 in format accommodates full-size booklets and multi-page brochures without folding, preserving a professional look.
• Material weight: The 80lb. text stock feels substantial and resists bending, which helps protect financial mailings and reports in transit.
• Closure: The peel & press flap provides a quick, reliable seal for high-volume mailings and reduces the time spent preparing shipments.
• Printable: These envelopes work with offset and digital presses and some home printers, letting users add addresses, logos or barcodes for branding and automation.
• Quantity: The pack of 500 offers good value for businesses or seasonal peaks such as tax season when high volumes are needed.

Who It's For

These envelopes suit small to mid-size businesses, accounting firms, non-profits and marketing teams that send catalogs, magazines, annual reports or W-2/1099 forms and prefer to mail documents flat. The teal color is useful for brand coordination or to set certain mailings apart in a stack.

Shoppers who need padded protection, waterproofing or rigid mailers should look elsewhere; for fragile items or irregular shapes a different mailer type is more appropriate. If an exact color match is critical, buyers should consider ordering a sample first, as some customers report variance in shade.
